The television rights to the NFL are the most lucrative and expensive rights not only of any American sport, but of any American entertainment property. With the fragmentation of audiences due to the increased specialization of broadcast and cable TV networks, sports remain one of the few entertainment properties that not only can guarantee a large and diversified audience, but an audience that will watch in real time.
Annually, the Super Bowl often ranks among the most watched shows of the year. Four of Nielsen Media Research's top ten programs are Super Bowls. Networks have purchased a share of the broadcasting rights to the NFL as a means of raising the entire network's profile.
Under the current television contracts, which began during the 2006 season, regular season games are broadcast on five networks: CBS, FOX, NBC, ESPN, and the NFL Network. Regionally shown games are broadcast on Sundays on CBS and FOX, carrying the AFC and NFC teams respectively (the traveling team deciding the broadcast station in the event of inter-Conference games, presumably so that each network can show games from all the stadiums). These games generally air at 1:00 p.m. ET and 4:00 p.m. or 4:15 p.m. ET. Nationally televised games include Sunday night games (shown on NBC), Monday night games (shown on ESPN), the Thursday night NFL Kickoff Game (shown on NBC), the annual Dallas Cowboys and Detroit Lions Thanksgiving Day games (CBS and Fox), and, as of 2006, select Thursday and Saturday games on the NFL Network, a wholly owned subsidiary of the National Football League.
Additionally, satellite broadcast company DirecTV offers NFL Sunday Ticket, a subscription based package, that allows most Sunday daytime regional games to be watched. This package is exclusive to DirecTV in the USA. In Canada, NFL Sunday Ticket is available on a per-provider distribution deal on both cable and satellite.
